Could it be the best way to grind CH??? i am commando 2/2/4/0 and if my friend doing CH lets me attack hard creatures 1st then, uses his baby pets lvl 15 on lvl 30 creatures he is getting 800xp per kill. Hope this is of sum help to you all. If any1 has any better ideas let me know as i have to do CH for my 2nd holo and grimace the thought.
